Defense & Resilience is the track for defensive engineering that directly disrupts attacker capability. We focus on preventive, architectural, and mitigation driven innovations that make exploitation harder, containment faster, and attacker tooling less effective. The focus is on universally applicable techniques and should rely or implicate a commercial product or service. Defensive innovations include isolation technologies (micro VMs, CHERI like models, browser or site isolation, sandboxing frameworks), exploit mitigations (CFI, memory tagging, hardening), defensive disruption techniques that interfere with attacker toolchains or automation, and cross environment defensive systems that reshape the economics of attack—such as automated containment, pre exploitation risk scoring, exploit path pruning, ephemeralization, or moving target defenses. If your research reduces the feasibility, reliability, or impact of exploitation before or during an attack, this is the right track. This track does not cover detection engineering, telemetry correlation, SIEM/EDR analytics, enterprise attack chains, identity abuse, OS/firmware/hypervisor mitigations, AppSec SDLC or secure coding practices, or cloud native IAM and attack paths.
